The Phantom Load Audit
The heaviest work in your week is the work you can't see.
There's a category of work that never makes it onto a task list. Nobody scheduled it, nobody owns it, and nobody bills for it — so it doesn't exist on paper.
It exists in your week, though. It's the reason Thursday evaporates and you can't point at a single thing you finished.
The audit
For the next seven days, log every task nobody assigned you. That list is your backend brief.
